Researchers are exploring the concept of high-latitude stratospheric aerosol injection as a potential method to preserve the Arctic. The feasibility and potential impacts of this approach are being studied, with some research suggesting it could be implemented using existing aircraft, while others raise concerns about practical limitations and potential risks. The idea is part of a broader category of geoengineering strategies aimed at cooling the planet, with various studies examining its potential effects on Arctic sea ice, atmospheric circulation, and ozone levels.
